Important deprecations, removals or restrictions:

Development team of Python improved its clarity of error messages in below Erros:

For Example:

Syntax Error

Previous version of interpreter Error message

In Latest Updated Error message is Exact(Which is wonderful)

Indentation Error

Structural Pattern matching lets you match variables against one of a set of possible values As switch/case in Java script language and it also allows you to match against pattern of values ex: an object with a certain property set to a certain value. This makes Structural Pattern Matching Very interesting and expands the endless possibilities and make it possible to write code that quickly encompasses a variety of scenarios

Example 1

Developers have added two new options to improve the information provided to static type checkers for ‘Callable’ to the ‘typing’ module. The first is the parameter specification variable which is used to forward the parameter types of one callable to another, a pattern usually found in higher-order functions and decorators.

The second one, the ‘Concatenate’ operator, is used in conjunction with parameter specification variables to annotate a higher-order callable which adds or removes parameters of another callable.

Python Developers Introduced new type union operator which enables the syntax X | Y. This provides a cleaner way of expressing ‘either type X or type Y’ instead of using typing.Union.
